has for its primary object and purpose the vconstruction of a slidewhich is very simple yeteffective to carry a drawer practically entirely outside of its enclosing case or cabinet, the slide having a progressive movement back and forth with the drawer so that when said drawer is 4wholly extended, the slides, one at each side of the drawer are extended one half of their length. A further object of the invention is to malte a metal construc- Y tion of drawer slide and provideit with a novel form of progressive movement construction, very simple in structure but oneV in which the action of the slide is especially smooth and easy. These features as well as many others not at'this point specifically' outlined will appear fully and in detail as understanding of the invention is had from the following description, taken in connection with the accompanying drawings, in which,

Fig. l is a partial section and side elevat-ion illustrating the construction and extension of the drawer slide, the drawer being indicated in dash outline that the slide construction may more fully appear.

nected by horizontal bars 2 are used, being' spaced apart and connected together by horizontal cross frames made up of transverse bars 3 connected by side bars t. This frame work may be enclosed by panels such as that shown at 5 at the back, and any suitable side panels if desired, leaving the front open for the insertion of the drawers.

The number of drawers in a case is a matter of choice, and the construction of the slides therefor for one applies to all. A channel member G is located horizontally above each side 4 of the transif'erse frames and against the horizontal members 2 of the cabinet side frames, the iianges of said channel member extendingfrom the web thereof toward said bars 2. The upper flange has a part at its free edge cut away thus making a slot 7 which extends the entire lengt-h of the channel. Inside of the channel member at its front end is a bar S of wood. This bar extends back substantially one half of the length of the channel member and is held in place by screws 9. A part of the bar 8 directly below the slot 7 is removed forming a groove as shown in Fig. 4.

A slide of met-al is located directly above the channel bar. The slide is formed of sheet metal and has a lip l0 at its lower edge which extends through the slot 7 in the channel G and rides in the groove in bar S. At its rear end the slide has an integral downward projection 1l which also passes through the slot 7 and on which a roller l2 is rotatably mounted, the same being wit-hin the channel member and designed to traverse the length thereof until stopped by coming against the rear end of the bar S, thereby limiting the extension of t-he slide in front of the case to about one half of its length.

Above the lower lip l0 ofthe slide a section 13 is pressed to come partially over the channel 6. .er roller la is mounted on this section at the front end of the slide and a second roller 15 is' rotatably mounted at about the middle point in the length of the slide on said section 13, the rollers being positioned so to ride on the upper flange of the channel member 6. Above the section'l, another section 16 is formed lengthwise of the slide and pressed so as to lie in the same vertical plane with the lower lip il). Above section 16. a section l is formed, bemg pressed inwardly so as to lie in a plane lOO llO

intermediate that ot' sections 13 and i6, while above section 17, still another section 18 is formed lying in the same plane with section 16 and lip 1 0. EL horizontal. ledge 19 is turned inwardly from the upper edge ot section 1S 'lor a distance, iroin the inner edge ot which an upper lip 2O is turned, its inner side lying' in the same plane as the inner sides oi? the rollers 1% and 15 and adapted to come against or very close to the sides ot the drawer carried by two olf the slides, one being located at each side ot the case or cabinet.

cluding sides 9,1 to which angle bars liormcd ot vertical legs 2:2 and projecting horizontal legs QB are secured, one at each side ot the drawer. Theleg 23 is curved downwardly from the rear end toward the middle, as shown in Fig'. 3, the curve being for substantially one halt the length ot the leg, the 'forward portion being straight. l roller 2li is mounted at the. rear end ol: the leg Q2 and is designed to bear against the under` side ol the ledge 19 while rollers il-'t and 15 come immediately below the leg 25%, which bears on them.

il. plate 25 is attached to each side 2l ot the drawer above the angle and a dog 2G is pivotally connected at its np per end thereto, riding on the upper sides ot the ledges 1G' oi' the two slides, as the drawer is drawn out. llear the front end ot each slide a stop 2T is cul; and turned :from the upper lip Qi), and over-the ledge 19. rlhe dogs coming to said stops when the drawer is drawnout, serve to limit the outward movement ot' the drawer and prevent disengagement ot the drawer trom the slides. The dogs QG may be readily li'lted, however, whenever it is desired to entirely remove the drawer.

VT his construction is relatively simple and may be inanni'factured at low cost, the parts beine' all ot sheet metal readily rolled, cut and formed into shape. As the drawer is pulled out, the leg 23 rides against roller l5 causing the same to turn and move along the upper flange oi" channel G, whereby the slide at each side ot the drawer moves lor- Vward carrying the drawer forward at the ward with respect to the slide. The weight ot the drawer andA contents is transmitted to the drawer slides through rollers 15 and 2st and from the slides to the channels 6 through rollers 12 and 15. Roller 12 runs on the upper and lower flanges of the channels 6, serving a double function depending on the position of the drawer, keeping it from tipping when extended and supporting the same when within the case. The 'torniation of the slides with various sections 13, 15, 17 and 1S set oil' into dillerent vertical planes makes a compact structure in which the rollers cannot move laterally, it being laica-see clear that roller Qd is disposed between the leg 22 and section l? and rollers lll and 15 between the sides ot the `drawer and sections 13 ot the'slide, the offsets of said sections being just sufficient to let the rollers pass freely but allowing :no-lateral movements. Theprogressive movements ot the slides with lthe drawer is a feature of novelty and merit and such movements are verye'liectively and practically accomplished. the drawer has an exceptionally smooth and easy movement. The placing ot the drawer be- Y -tween the slides is automatically accomrlhe drawer is ol usual construction .1n-A

plished, the dogs rising Vand riding over stops 27' and then dropping behind them. The construction is practical in Vevery respect.
